Mastic sealing in The Stocks

Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. The enquiries we see most involve brittle perimeter mastic across a building and draught complaints from residents or tenants, on external wall and movement joints, shopfronts below residential blocks and window and door perimeters on blocks. For commercial sealant work in The Stocks, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

In and around smaller places like The Stocks, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.

Work we carry out in Kent comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or email drawings and photos and we’ll come back to it.

Your questions answered

Can you quote for mastic across several buildings in and around The Stocks?

Yes, we quote for single buildings and for programmes across several blocks. Send the addresses and photos and we will give a fixed quote.

Is a smaller place like The Stocks outside your area?

No. Small places get the same service as large ones. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

How long does a job like this take?

That varies with the scale of the job, though a typical visit usually takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we’ll set out a timescale with the quote.

Do you guarantee the mastic work?

Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.

Does the weather affect the work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

What affects the price in The Stocks

A fixed quote reflects the actual work. It allows for:

  • Removal of failed or old sealant
  • Quantities, in metres or numbers
  • Travel to remote or island sites
  • The size and state of each joint

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Sending details for a quote

A good diagnosis starts with the right details. Let us know:

  • The type of building and who uses it
  • Specification clauses that apply
  • Anything awkward about access or site hours
  • The asbestos register, for older buildings

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Looking after buildings in and around The Stocks

The Stocks is about 49 miles from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. The Stocks is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and the sunniest, most exposed sides of a building usually need attention first.

Buildings close to stations like Rye station, 4.2 miles south of The Stocks, are often flats over shops, with frame mastic to keep sound. For a school such as Wittersham Church of England Primary School, perimeter mastic on windows and doors is a holiday job.

The Stocks is about 11 miles south-west of Ashford, in Kent. Businesses, contractors and managing agents in The Stocks can call on us for mastic joints. Across Kent, 931 places are covered, including The Stocks. Our Brighton page has more on work in that area, about 39 miles away.

Commercial clients in The Stocks

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. The Stocks can form part of a wider programme across Kent.

How the job changes by surface

Window and door perimeters on blocks

Frames vary from uPVC to aluminium and timber, and the product is matched to the frame material and the masonry. We will confirm the colours available for the specified product.

Tenement and older buildings

Older buildings, including Scotland’s sandstone tenements, have their own joint details. We look at the substrate before choosing a sealant.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like The Stocks are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  3. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

Preparing the site

  • Arrange parking or a loading space
  • Let us know about inductions and permits
  • Let building users know which areas are affected

Related advice

Leave it or put it right?

Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. Older rural buildings around The Stocks move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

When to call us in The Stocks

Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.

What tends to prompt an enquiry:

  • Damp patches beside frames
  • Brittle perimeter mastic across a building
  • A mix of products and colours from past repairs
  • Estate-wide sealant that is simply worn out

If you’re responsible for a building such as Parish Church of St John the Baptist, frame and door mastic needs the same attention as any other property.

What your quote should include

  • Who will actually carry out the work
  • Do they follow the manufacturer’s priming guidance?
  • Whether old or failed sealant will be cut out, not overlaid
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
